Definition
Trou aux Cerfs is a dormant volcanic crater located in the central highlands of Mauritius, near the town of Curepipe. It is a circular, bowl‑shaped depression formed by ancient volcanic activity.
Overview
The crater is part of the island’s volcanic landscape, which originated from a series of shield volcanoes that built Mauritius between 10 and 5 million years ago. Trou aux Cerfs is one of the few well‑preserved volcanic craters remaining on the island and is a popular site for tourists and local visitors. The area surrounding the crater includes a public park with walking trails and informative signage.
Etymology / Origin
The name is French, where trou means “hole” or “pit” and cerfs means “deer.” The literal translation is “Deer’s Hole.” The origin of the name is not definitively recorded; local tradition suggests that the crater’s shape or the presence of wildlife in the surrounding forest may have inspired the appellation.
Characteristics
- Geological formation: The crater is a volcanic maar formed by phreatomagmatic eruptions, where groundwater interacted explosively with magma.
- Dimensions: Approximately 300 m (≈ 980 ft) in diameter and about 80 m (≈ 260 ft) deep.
- Age: Estimates place its formation at roughly 300,000 years ago, during the later stages of Mauritius’s volcanic activity.
- Vegetation: The crater slopes are covered with native and introduced plant species, including shrubs, grasses, and small trees, creating a modest arboreal environment.
- Accessibility: A paved footbridge and a network of trails provide access to the crater rim and allow visitors to view the interior from observation points.
- Conservation status: Managed by the Mauritian Ministry of Tourism and the Ministry of Environment, the site is maintained as a public park and is subject to conservation measures to prevent erosion and preserve its natural state.
